Trump spoke during a roundtable Friday at Luke Air Force Base in Arizona with defense industry executives and local business leaders. He's in Arizona to help stump for McSally.

The two congresswomen are vying for the seat of Republican Sen. Jeff Flake, who is retiring. McSally was a Trump critic in 2016 and represents a Tucson district that voted for Democrat Hillary Clinton.

She's now embraced the president and hopes his visit to Arizona helps unites Republicans against Sinema.
